Abstract

The invention relates to a rotor-type internal-compression oil-gas mixed transport pump unit, and belongs to the technical field of fluid transportation devices. The unit comprises a housing which supports a pair of conjugated rotors engaged with each other; the cavity in the housing is partitioned by the conjugated rotors into an inhalation chamber and a discharging chamber; the inhalation chamber is equipped with a fluid inlet, and the discharging chamber is equipped with a fluid outlet; the discharging chamber is partitioned into an engaging area and a discharging area by an isolating wallwhich is disposed between the conjugated rotors and the fluid outlet; at least one one-way valve is disposed at the isolating wall; when the one-way valve is closed, the engaging chamber is completely isolated from the discharging chamber are; when the one-way valve is opened, the engaging chamber is communicated with the discharging chamber. Even in a multiphase medium transporting process with an unstable gas-liquid ratio, the rotor-type internal-compression oil-gas mixed transport pump unit of the invention has the unique function of internally compressing the gas medium, pressurizing the gas to a discharging pressure so as to discharge the gas out of the pump; the invention can completely eliminate the gas blocking phenomenon, and can reliably realize the internal-compression transporting process of the transported multiphase medium.

Description

technical field [0001] The invention relates to a pipeline conveying device, in particular to a conveying pipeline driving device. Background technique [0002] While vigorously developing pressurized water reactor nuclear power plants, my country is also actively developing high-temperature reactor nuclear power plants. High-temperature reactor nuclear power plants are recognized as nuclear power plants with the main characteristics of fourth-generation nuclear power, with inherent safety, nuclear proliferation prevention, and high-temperature process heat generation. advantage. The pebble bed high temperature gas-cooled reactor uses spherical fuel elements, and coated fuel particles are dispersed in the spherical fuel elements. The diameter of the coated fuel particles is about 1 mm. Spherical fuel element is to fully mix a certain amount of fuel particles and matrix graphite, press it into a graphite ball with a diameter of 50mm, and then wrap and press a layer of pure g...
